WINDOW OR' DOORSCREEN. a

SPECIFICATION forming part of Letters Patent No. 737,307, dated August 25, 1903. Application filed November 1, 1902. Serial No. 129,656. (No model.)

' screen that flies or other winged insects may readily pass out from a room, but will be effectually prevented from flying or crawling in through the openings prepared for their exit.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out inthe claim. 7

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a screendoor embodying the features of my invention, parts being broken away. Fig. 2 is a horizontal section taken practically on the line 2 2 of Fig. 1,.and Fig. 3 is an enlarged transverse section taken practically on the line 3 3 of Fig. 1.

A represents a screen-door divided into two screen-panels B and B by a transverse partition 0. This partition and likewise the top transverse member D of the frame are similarly shaped at their outer faces, which faces, as is particularly shown in Figs. 1 and 3, are provided with an upper longitudinal concaved recess 10, separated by a plain" or straight surface 11 from a lower downwardly and inwardly inclined recess 12. The screen material 13 is attached to the outer surface of the frame in any approved manner, and the upper edge of the said screen material, forming the panel, terminates near the upper portion of the upper concaved recess 10 in the transverse member of the frame of the same panel, whereby an opening 14 for the exit of insects is formed between the upper portion of the recess 10 and the upper edge of the'screen material. Battens or posts 15 are placed at intervals between the screen material 13 and the. plain or straight surfaces 11 at the recessed portions of the transverse members of the frame to support the trans-. verse strips 16, utilized to strengthen and stay the upper ends of the panels of screen material and to preserve intact the passages between the lowerrecesses 12 and the upper recesses lO in the frame. Finally guardstrips 17, preferably of a reticulated or per forated material, are located between the posts 15 and intermediate plain surfaces 11 of the recessed portions of the frame, which guard-stripsextend from one side piece of the frame to the other and above the posts 15 within the upper recesses 10 out of engage- Inent with their walls, usually to the same height as the upper edges of the screen material, as is best shown in Fig. 3.

In operation the flies in a room may readily find an exit through the passages between the screen material 13, the recess portion 12, pass the portion 11, of the frame, and out at the openings 14; but an insect endeavoring to enter the room through the same channel if flying would strike the upper portion of the guard 17, and should the insect endeavor to crawl down the upper concaved recess 10 its downward passage would be stopped by the guard 17, which acts as a barrier.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination with a door-frame, comprising side rails and connecting top and bottom rails, said top rail having a concave groove formed thereon contiguous to the upper longitudinal edge thereof, the lower edge portion of said rail being beveled or concaved parallel to the upper groove, whereby a projecting strip or bead is formed between the grooves,,a guard-strip secured to the bead, the upper edge of said strip extending above said bead, an open space being left'between the upper edge of the strip and the upper edge of the top groove, spacing-blocks fas- I name to this specification in the presence of tened to said bead, and a panel formed with a two subscribing Witnesses. body portion of screen-like material, secured to the main frame of the door, the upper edge 5 of said panel being secured to the blocks, subi Witnesses:

stantially as set forth. OSCAR V. LINDEN,

In testimony whereof I have signed my FRED WILDI.
